问题 单项选择题

关于腹膜的解剖生理,错误的是()

A.成人腹膜总面积可达2m2

B.正常腹腔可有100ml液体

C.腹腔有强大吸收力

D.腹膜可分泌大量渗出液

E.脏腹膜比壁腹膜痛觉敏感

答案

参考答案:E

解析:正常情况下,腹腔内有75~100ml黄色澄清液体,起润滑作用。腹膜向腹腔内渗出少量液体,内含淋巴细胞,巨噬细胞和脱落的上皮细胞。腹膜有强大的吸收能力,能吸收腹腔内的积液,血液,空气和毒素等。壁层腹膜主要受体神经的支配,对各种刺激敏感,痛觉定位准确;脏层腹膜受自主神经支配,来自交感神经和迷走神经末梢,对牵拉,胃肠腔内压力增加或炎症,压迫等刺激较为敏感,其性质常为钝痛而定位差。
